Carriers components class.
This class is used for carrier components. All functionality specific to carriers is implemented here. Functionality for all components is implemented in the abstract base class.

'Carrier' Components
--------------------
Attached to PyPSA Network 'AC-DC-Meshed'
Components: 6

-
addβAdd new carriers.

pypsa.components.Carriers.add
ΒΆ
add(name: str | int | Sequence[int | str], suffix: str = '', overwrite: bool = False, return_names: bool | None = None, **kwargs: Any) -> Index | None
Add new carriers.
Handles addition of single and multiple components along with their attributes. Pass a list of names to add multiple components at once or pass a single name to add a single component.
When a single component is added, all non-scalar attributes are assumed to be time-varying and indexed by snapshots. When multiple components are added, all non-scalar attributes are assumed to be static and indexed by names. A single value sequence is treated as scalar and broadcasted to all components. It is recommended to explicitly pass a scalar instead. If you want to add time-varying attributes to multiple components, you can pass a 2D array/ DataFrame where the first dimension is snapshots and the second dimension is names.
Any attributes which are not specified will be given the default value from Components.
Parameters:
-
name(str or int or list of str or list of int) βComponent name(s)
-
suffix(str, default:"") βAll components are named after name with this added suffix.
-
overwrite(bool, default:False) βIf True, existing components with the same names as in
namewill be overwritten. Otherwise only new components will be added and others will be ignored. -
return_names(bool | None, default:None) βWhether to return the names of the new components. Defaults to module wide option (default: False). See
https://go.pypsa.org/options-paramsfor more information. -
kwargs(Any, default:{}) βComponent attributes to add. See Other Parameters for list of default attributes but any attribute could be added.
Other Parameters:
-
co2_emissions(float or SeriesLike[float]) βEmissions in tCO2 per MWh of primary energy (e.g. methane has 0.2 tCO2/MWhthermal).
-
color(str or SeriesLike[str]) βColor for plotting (e.g.
matplotlibnamed colors or hexadecimal color codes like "#AB9812") -
nice_name(str or SeriesLike[str]) βDescriptive name for statistics and visualisations (e.g. "Natural Gas" for carrier
gas) -
max_growth(float or SeriesLike[float]) βMaximum new installed capacity per investment period
-
max_relative_growth(float or SeriesLike[float]) βMaximum capacity ratio for new installed capacity per investment period
Returns:
-
new_names(index or None) βNames of new components (including suffix) if return_names is
True, otherwiseNone.
Examples:
The example is shown for Generator component, but the same applies to all component types.
>>> n = pypsa.Network()
>>> c = n.components.generators
>>> c
Empty 'Generator' Components
Add a single component:
>>> c.add("my-generator-1", carrier="AC")
A new generator is added to the components instance:
>>> c
'Generator' Components
----------------------
Attached to PyPSA Network 'Unnamed Network'
Components: 1
With static data (and default values for all attributes):
>>> c.static[["carrier", "p_nom"]]
carrier p_nom
name
my-generator-1 AC 0.0
Add multiple components with static attributes:
>>> c.add(["my-generator-2", "my-generator-3"],
... carrier=["AC", "DC"],
... p_nom=10)
A new generator is added to the components instance:
>>> c
'Generator' Components
----------------------
Attached to PyPSA Network 'Unnamed Network'
Components: 3
With static data:
>>> c.static[["carrier", "p_nom"]]
carrier p_nom
name
my-generator-1 AC 0.0
my-generator-2 AC 10.0
my-generator-3 DC 10.0
The single value for p_nom is broadcasted to all components. So you could also
pass [10, 10] instead of 10.

pypsa.components.Carriers.add_missing_carriers
ΒΆ
add_missing_carriers(**kwargs: Any) -> Index
Add carriers that are used in the network but not yet defined.
This function iterates over all components that have a carrier attribute, collects all unique carrier values, and adds any carriers that are not yet defined in the network.
Parameters:
-
**kwargs(Any, default:{}) βAdditional keyword arguments to pass to the add() method for the new carriers (e.g., color, co2_emissions, nice_name).
Returns:
-
IndexβIndex of newly added carrier names.
Examples:
>>> n = pypsa.Network()
>>> n.components.buses.add('my_bus', carrier='my_carrier')
>>> n.c.carriers.add_missing_carriers()
Index(['my_carrier'], dtype='object')
Carriers are added without needing to call n.add separately:
>>> n.components.carriers.static
co2_emissions color nice_name max_growth max_relative_growth
name
my_carrier 0.0 inf 0.0
pypsa.components.Carriers.assign_colors
ΒΆ
assign_colors(carriers: str | Sequence[str] | None = None, palette: str = 'tab10', overwrite: bool = False) -> None
Assign colors to carriers using a matplotlib color palette.
Parameters:
-
carriers(str, Sequence[str], or None, default:None) βCarrier name(s) to assign colors to. If None, assigns colors to all carriers that don't have a color set (or all if overwrite=True).
-
palette(str, default:"tab10") βMatplotlib color palette to use for assigning colors. Options include: - "tab10" (10 colors, default) - "tab20" (20 colors) - "Set1", "Set2", "Set3" (qualitative palettes) - "Pastel1", "Pastel2" (soft colors) - Any other matplotlib colormap name
-
overwrite(bool, default:False) βIf True, overwrite existing colors. If False, only assign colors to carriers that don't have a color set (empty string or NaN).
